UNITED STATES PATENT OFFICE.

ROBERT C. ANDERSON, OF BAYONNE, NEW JERSEY.

BOX-TRIMMING MACHINE.

SPECIFICATION forming part of Letters Patent No. 277,100, dated May 8, 1883,

Application filed November 18, 1882. (No model.)

To all whom it may concern Be it known that I, ROBERT C. ANDERSON, of Bayonne, in the county of Hudson and State of New Jersey, have invented a certain new and useful Improvement in Machines for Trimming Boxes, of which the followingis a specification.

This improvement relates to machines for trimming wooden boxes or packing-cases to a uniform size.

The improvement consists in various combinations of parts hereinafter described and claimed.

Although the improvement has especial relation to machines for trimming boxes, certain features may be applicable for other purposes.

In the accompanying drawings, Figure 1 is a central longitudinal section of a machine embodying ,my improvement. Fig. 2 is a transverse section of the same, and Fig. 3 isa horizontal section thereof. v

' Similar letters of reference designate corre sponding parts in all the figures.

A designates the frame. It may be, of any desirable material and of any approved construction.

B designates a carrier for the boxes to be trimmed. It consists of an endless apron supported by two pulleys, B, one of which deguided.

rives motion from any suitable source to impart motion to the belt. The upper part of this carrier passes over a bed, 0, which is provided with rails (1., whereby the carrier is At intervals the outer side of the carrier is provided with a number of ribs, 1), which press against the rear sides of theboxes to impel them forward. upon the carrier from a feed-table or otherwise, and they'are delivered by the carrier onto a delivery-table, D. The boxes are shown as arranged on the carrier upside down. When they arrive at the rails a they ride up on the same and are supported thereby. They pass between side guides, E, which preferably are furnished with ribs 0, which bear against the boxes. Springs may be employed in lieu of and in the position occupied by these ribs. A

presser, F, keeps the boxes down. It is connected to the side guides, E, and is provided on the under side with springs d, which im- The boxes may be placed pinge on the boxes. The side guides are connected to standards E, having slotted feet sccured to the frame A by screw-bolts, so as to enable the side guides to be adjusted toward or from each other to adapt the machine for .boxes' of different sizes.

The presser is connected to the side guides by angle-pieces'F, slotted alongboth limbs, and secured to the side guides and presser by bolts passing through the slots. Provision is thus afforded for elevating or lowering the presser as well as varying the relation of the sides to it.

The trimming-saws are mounted on swinging arbors .G, which are supported in frames G, connected by hinges e to the frame A. These frames are capable of swinging in horizontal planes to move the arbors Gr toward and from each other. These frames may be adjusted in various ways to cause the saws to operate properly on the boxes. 1 have shown one of them as provided with a tail-piece, which is fitted with a screw,f, having a bearing on the frame A behind the hinges; A tailpiece and screw may be used on each frame. When a tail-piece and "screw is. employed on one frame only, a spring, 0, is attached to the frames or the saw-arbors to draw the latter toward each other. By turning the said screw or screws the saws may be adjusted relatively to the side guides. Preferably I employ a gage to insure the proper relation between the saws and the boxes. 1 have shown a gage, H, consisting of a spring attached at one end to the side guide, and impinging through an aperture in the side guide against the side of the boxes.

In connection with the arbors G, I. employ saws I and cutters J. The saws I serve to trim those edges of the sides of the boxes which are down while the boxes are in the machine, whereas the cutters J serve totrim or bevel off the edges of those parts which form the tops of the boxes while they are in the machine.

The saw-arbors may be rotated in any suit- 9 other words, in a direction opposite to that in which the boxes travel.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination of a carrier, saws mounted on parallel adjustable arbors on opposite sides of said carrier, means acting on said arbors to move them automatically toward each other, and a gage connected with one of said arbors, and against which the boxes to be trimmed will impinge, so as to regulate the position of the arbors, substantially as specified.

2. The combination of a carrier, rotary arbors which are parallel with each other, and which will be parallel with the sides of boxes passed between them, saws mounted on said arbors in such position that they can square off the edges of boxes which are lowermost as the boxes pass through the machine, and beveled cutters, also mounted on the arbors, and serving to bevel off the edges of the boxes which are uppermost as they pass through the machine, substantially as specified.

3. The combination ofacarrier, saws mounted on parallel arbors on opposite sides of said carrier, frames in which said arbors are supported, and which are pivoted so as to swing toward and from each other in horizontal planes, means for moving said arbors and frames automatically toward each other, and means for regulating such movement, substantially as specified.

4. The combination of an endless carrier consisting of a belt and a number of projecting ribs, a bed over which said carrier moves, and which sustains the same,rails serving to guide the carrier and to support boxes above the belt portion thereof, and saws mounted on adjustable arbors on opposite sides of said carrier, and serving to trim off the edges of the boxes which arelowermost as they pass through the machine, substantially as specified.

5. The combination of an endless carrier, parallel arbors arranged on opposite sides thereof, and carrying saws for trimming the edges of the boxes which are lowermost as they pass through the machine, frames supporting said arbors and pivoted so that they may swing in horizontal planes toward and from each other, and yielding guides for guiding the boxes as they pass the said saws, substantially as specified.
